NON-REFILLABLE 'no'rTLE.

T 0 all whom it may concern:

Be it known that 1, JOHN J. ROBINSON,

a citizen of the United States, residing in the city of New York,borough and county of Bronx, in the State of New York, have invented acertain new and useful I1nprovement-in Non-Refillable Bottles, of whichthe following is a specification.

V The invention relates to that class of closures in which a springactuated disk-valve is employed, and the object of the invention is toprovide a simple and efficient device which may be economicallymanufactured and easily assembled, and w-hichwill permit the containedliquid to flow freely from the bottle, and effectually preventrefilling.

The invention consists in certain novel features and details ofconstruction and arrangement by which the above objects are attained, tobe hereinafter described and claimed.

The accompanying drawings form a part of this specification and show anapproved ll respectively. Fig. 5 is a plan view of Fig. 6 is acorresponding the bafiie-disk. side elevation. Fig. 7 is a View of theunder face of the same.

Similar letters of referenceindicate the same parts in all the figures.I

A is the upper portion of a bottle, constructed with a short neck A onwhich the closure is mounted and shaped to form a continuation thereof.prises two main portions one above the other; on the neck A is cementedthe lower portion consisting of an annular shell B having a centralopening I; surrounded by a lip B serving as a valve-seat for thediskvalve D, and having an annular channel exterior to the lip and belowthe latter. Above the shell B is the second portion or cap C having anannular skirt 0 the lower face of which is applied upon and cemented tothe shell B.

The cap has a pouring orifice, 0 closed by a cork G, connected by acontracted passage 0 with a circular recess 0 in the lower face havingan annular shoulder or offset C receiving the arms E projecting from thev and adjacent thereto.

The valveD' has ;a -stem D extending downwardly through .a guide orspider The closure comperiphery of a baffle-d-isk E of larger diameterthan the passage partially closing the recess '0 and held central-1ythereof by its arms which are cemented to the shoulder, C Onthe lowerface of the baffle-disk is a depending annular flange or"inv"erted cup Eterminating above the valve-seat B Specification of'L'etteislPatent.

frame B in the opening I), and asimilar stem D extending upwardly andaxially 1 of the cup. E is received in an axial hole in a boss E withinthe cup. A light delicate helical spring F encircles the portion D ofthe valve-stem and is partially inclosed in the cup E it abuts withinthe latter at its upper end, and at the lower end 'upon the upper faceof the valve D, tending by itsslight expansive force to urge the valveto itsseat.

Whenithe corkGris removed and the bottle tilted the pressure of thevalve D upon its seat, due to gravity, is lessened and the force of theliquid overcomes the resistance offered by the spring F, permitting theliquid to flow through the opening I) to the annular space 0* exteriorto the cup E whence it passes through one or more of the passages 0between the'arms E of the bafiie-disk E to the recess 0 and through thepassage 0 to the pouring orifice c. The movement of the liquid past thevalve causes the latter to apply upon the edge of the cup E as upon avalve-seat, and thus form a closed spring-chamber in. which the springis inclosed and contact of the liquid 'with the spring is prevented. Tofacilitate such sealing of the spring-chamber or cup, the valve D isprovided on its upper face with an annular groove (Z matching the skirtor lip of the cup; and within the groove is an annular ridge D forming acircular cavity of the same, or slightly smaller, diameter than thespring F and serving to engage the lower endof the latter. In attemptingto refill the bottle the inflow of liquid, aided by the spring F forcesthe valve to its seat and closes the opening 6 as will be understood,and the arrangement of the passages 0 with the baflledisk E, relativelytothe pouring orifice 0- and valve D, prevents tampering with the latterby the introduction of wires or other instruments through the pouringorifice. The annular channel 72 serves as a receptacle for the smallquantity of liquid which flows back through the pouring passages whenthe bottle is restored to its upright positioinand holds such liquid outof contact with the spring.

The parts B and C may be slightly conical or tapered externally, asshown, to simulate the usual form of bottle neck, and are joined to eachother and to the neck A of the bottle by a suitable cement, and theseportions are preferably inclosed in a slightly tapered-sleeve H of thinmetal or heavy foil matching to and cemented thereon for purposes ofreinforcement and ornamentation.

Importance is attached to the inverted cup E and its coaction with thevalve D in forming a closed chamber for the spring F during the pouringoperation and thus avoiding contact of the liquid with such spring.

The shell B, cap C and valve D are preferably of porcelain or'analogousmaterial, and the spring F is of metal preferably non-corrosive inrespect to the liquid contained in the bottle.

I claim The improved nonrefillable bottle herein described, comprising ashell having an with a contractedpassage and an annular l recess formingan annular shoulder, a battle disk having armsv engaging said shoulder,

said bafile disk having a depending inverted cup terminating above saidvalve seat, a

valve movable between the valve seat and the lower end of said cup andhaving upwardly and downwardly extended guiding stems, a guide withinsaid shell for the lower stem and a guide within said cup for the upperstem, and a spring interposed betweenthe cup and valve, said valve beingadapted to be seated against said seat when in one position and to seatagainst the adjacent end of the cup when the resistance of the spring-isovercome by the force of the liquid when the bottle is tilted.

In testimony that I claim the invention above set forth I affix mysignature, in presence of two witnesses.

JOHN J. ROBINSON.
